Import Energy-Saving Ball Mill — Buy in Bulk from Supplier in China

The Energy-saving ball mill from Shanghai Woshan Heavy Industry Machinery Manufacturing Co., Ltd. is a horizontal cylindrical grinder with an adjustable speed drive system, designed to reduce specific energy consumption by up to 25% through optimized internal lift geometry. It features a dual-bearing support structure and a variable frequency drive (VFD) to match torque output to material load, enabling smoother operation and reduced mechanical stress.

The mill accommodates grinding media from 15mm to 100mm diameter steel balls, with a standard filling rate of 30% ± 2%. The internal surface uses wear-resistant alloy steel with a hardness of HRC 58 to 62, typical for high-efficiency grinding applications. This mill supports both batch and continuous operation, with feed sizes up to 30mm and discharge sizes adjustable between 50 and 180 microns, depending on grinding duration and media size.

This equipment is commonly used in cement plants, mineral processing facilities, and chemical labs requiring fine particle size reduction. Buyers typically order units with 110kW to 800kW motor ratings. The supplier offers FOB Shanghai and CIF terms, with MOQ of one unit. Lead time is estimated at 50 to 60 days. Buyers should confirm whether the VFD is certified for industrial use under IEC 61800 and whether the control panel is dust-protected.
